WHAT IT DOES

What webhooks does on OpenClaw

AI agents use webhooks to create or update resources in OpenClaw, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OpenClaw environment.

RISK

Why webhooks is rated Medium

Webhook tooling typically involves creating, updating, or managing webhook endpoints and subscriptions (Write-level operations). However, the description is extremely vague ('helpers and integrations'), so the exact capability is unclear.

From the tool's definition Tool name 'webhooks' and description 'Webhook helpers and integrations' — description is vague and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs webhooks safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OpenClaw, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For webhooks, this is the rule to start with:

webhooks Rate-limited

webhooks stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

}

The button opens the PolicyLayer dashboard: create your workspace, connect OpenClaw, apply this rule, and every webhooks call is checked against it from then on.
